Objective To investigate the safety and feasibility of totally laparoscopic radical resection of gallbladder cancer.Methods The retrospective cross-sectional descriptive study was adopted.The clinical data of 30 patients who underwent laparoscopic radical resection of gallbladder cancer at the Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2013 to August 2015 were collected.The patients received synchronous hepatic segmental or extrahepatic bile duct resection according to the conditions of patients,and choledochojejunostomy was applied to patients undergoing extrahepatic bile duct resection.The patients accepted postoperative adjuvant chemotherapy according to the results of postoperative pathological examination.Observation indicators included (1) operation situations,including surgical procedures,operation time,volume of intraoperative blood loss and number of lymph node dissected,(2) postoperative situations,including time for outoff-bed activity,time for diet intake,time of drainage tube removal,occurrence of complications and duration of hospital stay,(3) results of postoperative pathological examination,including tumor stage and surgical margin,(4) postoperative adjuvant treatment,(5) follow-up situation including the survival of patients,tumor recurrence and metastasis.The follow-up using outpatient examination and telephone interview was performed to detect the survival of patients and tumor recurrence and metastasis up to December 2015.Count data were represented as average (range).Results All the 30 patients underwent successful laparoscopic radical resection of gallbladder cancer combined with hepatic S4b and S5 resection + lymph node dissection at N1 region.Six patients with obstructive jaundice caused by tumor invaded to extrahepatic bile duct underwent combined laparoscopic extrahepatic bile duct resection + Roux-en-Y hepaticojejunostomy,without perioperative death.The average operation time,average volume of intraoperative blood loss and average number of intraoperative lymph node dissected were 238 minutes (range,178-430 minutes),250 mL (range,200-600 mL) and 7 (range,4-15),respectively.(2) The patients got out-off-bed activity and normal diet intake at postoperative day 2,with a average time of drainage tube removal of 3 days (range,0-25 days) and an average duration of hospital stay of 5 days (range,3-28 days).Two patients with complications were cured by symptomatic treatment.(3) Results of postoperative pathological examination showed that all the patients received R0 resection,and pathological stage showed that 12 patients were detected in Ⅰ B stage,10 in Ⅱ stage,7 in ⅢA stage and 1 in ⅢB stage.(4) One patient in Ⅲ B stage (pT3N1 M0 stage) received gemcitabine + cisplatin chemotherapy and other patients didn't receive the adjuvant treatment.(5) All the patients were followed up for a median time of 16 months (range,4-32 months),without tumor recurrence and metastasis at Trocar puncture site.There were 25 patients with tumor-free survival and 5 patiens died of tumor recurrence.Conclusion Laparoscopic radical resection of gallbladder cancer is technically safe and feasible,with a satisfactory short-term outcome.

The NSP2 gene of porcine reproductive and respiratory syndrome virus (PRRSV)S1 strain was partly amplified and cloned into a prokaryotic expression vector pGEX-6P-1 and a fusion protein GST-tNSP2 with molecular weight of 50 kDa was expressed in E.coli. The purified GST-tNSP2 protein showed a strong reaction with the PRRSV-positive sera in Western blot assay. Balb/c mice were immunized with the purified protein, and the splenocytes of the immunized mice were fused with murine myeloma cells SP2/0. After subcloning by 3 times, two hybridoma clones which produced McAbs steadily were screened by ELISA, named 3H3 and 2B5. They all reacted strongly with the PRRSV S1 infected Marc-145 cells in IFA, but not with the PRRSV SY0608 strain. Both of the McAbs belong to IgG1 isotype, and their light chains belong ? type. The expressed GST-tNSP2 protein and McAbs could be used for identification of PRRSV isolates and functional analysis of NSP2.

Objective To compare the curative effect of high ligation+exfoliation and subfascial endoscopic perforator surgery(SEPS)for superficial varicose veins in calf+invagination spot-striping surgery in great venous varicosity.Methods Study group(42 patients)accepted SEPS+invagination spot-striping surgery and control group (42 patients)accepted traditional surgeries.Operation duration,bleeding volume in operation,the time of beginning movement away from bed after operation,hospitalization duration,the degree of pain,the scar,the recrudescence af- ter operation and the instance of the ulcer heals of two groups were compared.Results Operation duration,bleeding volume in operation,the time of begin movement away from bed after operation and hospitalization durations of study group were significantly lower than those of control group(P0.05).All of the patients in study group recovered without severe syndromes such as venous thrombosis,skin necrosis,lower limb functional disorder etc.They had no recrudesce after 4～16 months and were satisfied with the curative effect.Con- elusions The clinical curative effect of SEPS+invagination spot-striping surgery in great venous varicosity is superi- or to that of traditional operation and it has the advantages such as minor wound,few scars,light pains,short hospi- talization duration,without recrudescence,the ulcer heals quickly and so on.

In this paper, the action of suet oil in the preparation of self-assembled micelles of the active flavonoids in Epimedium in the simulated human environment was researched. Twelve suet oil samples were collected from different growing areas and different positions of sheep or goat to simulate the formation of micelles. Then the effects of the fatty acids in suet oil on the preparation of self-assembled micelles were studied furthermore. The results showed that the micelles had a dispersed state and spherical smooth surface. To compare the diameter, potential, encapsulation efficiency and drug loading of the 12 batches micelles, the micelles prepared by the suet oil from Qinghai were more stable and had a higher encapsulation efficiency. The fatty acids in suet oil could promote the formation of self-assembled micelles, but the whole suet oil had a better effect. Above all the study, we confirmed that the suet oil promoted the formation of self-assembled micelles of the flavonoids in Epimedium, it laid foundation for further research about increasing the efficacy of Epimedium and improved the absorption of the active flavonoids in Epimedium.

OBJECTIVETo observe the efficacy and safety of modified Shengma Biejia Decoction (MSBD) combined with CAG program in treating elderly acute myeloid leukemia (AML) patients with yin deficiency toxin stasis syndrome (YDTSS).

METHODSTotally 46 elderly AML patients were assigned to the treatment group (24 cases; treated with MSBD + CAG) and the control group (22 cases; treated with CAG + placebos of Chinese medicine) according to random digit table. The therapeutic course of CM placebo or MSBD was 21 days. The clinical efficacy and adverse reactions were observed. Meanwhile, physical state (ECOG Score), transfusion dependency, and TCM syndrome score were compared before and after treatment.

RESULTS(1) The complete remission rate was 54% (13/24) and the objective response rate (ORR) was 71% (17/24) in the treatment group, obviously higher than those of the control group [36% (8/22); 54% (13/24)], with statistical difference (P = 0.036, 0.042). When comparing the efficacy based on risk level, the moderate and poor ORR was 71% (10/14) and 67% (6/9) in the treatment group, and 57% (8/14) and 33% (2/6) in the control group, with statistical difference between the two groups (P = 0.048; P = 0.010). (2) Compared with before treatment in the same group, the ECOG score significantly decreased, the average infusion time of red cells and platelets were markedly prolonged in the treatment group after treatment (P < 0.05). ECOG score, the average infusion time of red cells and platelets were significantly better in the treatment group than in the control group after treatment (P < 0.05). (3) Compared with before treatment in the same group, scores of fever, hemorrhage, and bone pain were markedly reduced in the control group (P < 0.05); scores of fever, fatigue, hemorrhage, dry mouth, and bone pain were markedly reduced in the treatment group (P < 0.05). Better effect in relief of fever, fatigue, hemorrhage, dry mouth, and so on was obtained in the treatment group than in the control group (P < 0.05). (4) In aspect of hematotoxicity, the incidence of neutropenia, anemia, thrombocytopenia was obviously lower in the treatment group than in the control group [29.2% (7/24) vs 54.5% (12/22); 16.7% (4/ 24) vs 45.5% (10/22); 33.3% (8/24) vs 63.6% (14/22); P < 0.05]. The incidence of fatigue and anorexia was obviously lower in the treatment group than in the control group [37.5% (9/24) vs 63.6% (14/22), 37.5% (9/24) vs 81.8% (18/22); P < 0.05].

CONCLUSIONMSBD combined with CAG program in treating elderly AML patients with YDTSS, with efficacy enhancing toxicity reducing effect, had distinct advantages in improving physical condition and clinical symptoms, and reducing transfusion dependency.
